5.7 hemi crank but no start.

08 hemi 5.7 with 6.1 topend. Hotwire harness and Bouchillon performance ecu and sensors.
I got crank, spark, and can hear the fuel pump prime, and throttle movement. But no start. Every once in a while I'll get a pop fire out the header.

Alittle frustrated, not sure what to check.
